Abstract
A state-of-the-art laser diode simulation tool has been used to investigate how phonon reflection at epitaxial interfaces impacts upon the performance of high-power 980 nm ridge waveguide lasers. Due to the inclusion of phonon reflection, a 0.5 K increase in quantum well temperature and a reduction in front facet output power of up to 0.6 mW is observed. The results demonstrate that whilst this effect is relatively small, a first order correction should be made to obtain accurate simulation results.
